Jailed for 10 years for possessing murder weapon
'SCARRED' O'BRIEN ALREADY GIVEN LIFE SENTENCE
BRAY MAN Garrett O'Brien has been sentenced to 10 years for possession of a gun he used to murder Tallaght man Seamus O'Byrne.
O'Brien was recently sentenced to life in prison for the murder, which occurred on March 13 2009.
He gunned down Mr. O'Byrne in front of his partner and their sun.
O'Brien pleaded not guilty both to the murder and having the gun with intent to endanger life.
His trial at the Central Criminal Court lasted five weeks before a jury found him guilty. The sentences were both backdated to March 4, 2010, when O'Brien entered custody.
The Court heard that O'Brien had never managed to break the cycle of heroin addiction developed from an early age, which had left him vulnerable to exploitation by criminal elements.
Counsel Feargal Kavanagh SC added that O'Brien has a permanent scar across his face after being seriously attacked by a fellow inmate with a double- bladed knife.
Ms. Justice Iseult O'Malley agreed that drug addiction was the primary cause of Garrett O'Brien falling into the company of those who had conspired to murder Séamus O'Byrne.
The trial heard that while O'Brien was the gunman, he was one of a gang of men who had planned to kill Mr. O'Byrne.
Séamus O'Byrne's sister Charis said her brother had been a 'constant light' in the lives of his family, partner Sharon and two children Ricky and Jody.
' He was a very happy- go- lucky, loving person who didn't deserve to die the way he died,' she said.
